A 4 V/µs slew rate and 1.3 MHz -3 dB bandwidth mean this part handles moderate-speed data acquisition without trading off DC precision. The 2 nA input bias current keeps the voltage error across source impedances low — relevant when the sensor bridge impedance runs into the kΩ range. That covers standard 5 V and ±15 V industrial rails without a secondary regulator.","metaTitle":"INA128UAE4 Instrumentation Amplifier, 25 µV Offset","metaDescription":"TI INA128UAE4 precision instrumentation amplifier: 25 µV input offset, 4 V/µs slew rate, 1.3 MHz bandwidth, -40 to 125°C.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Analog & Data Acquisition"],"specifications":{"Mfr":"Texas Instruments","Series":"-","Package":"Tube","Slew Rate":"4V/µs","Output Type":"-","Mounting Type":"Surface Mount","-3db Bandwidth":"1.3 MHz","Amplifier Type":"Instrumentation","Package / Case":"8-SOIC (0.154\\\", 3.90mm Width)","lifecycle_stage":"eol_hot","Current - Supply":"700µA","Number of Circuits":"1","Base Product Number":"INA128","Current - Input Bias":"2 nA","Operating Temperature":"-40°C~125°C","Voltage - Input Offset":"25 µV","Supplier Device Package":"8-SOIC","Current - Output / Channel":"15 mA","Voltage - Supply Span (Max)":"36 V","Voltage - Supply Span (Min)":"4.5 V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$7.4700","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/38ef53acfab362c1f4307adc148d9e91.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/INA128UAE4/alternatives.json"},"ai":{"faq":[{"question":"What is INA128UAE4 used for?","answer":"As an instrumentation amplifier, it is used for conditioning small differential signals from bridge sensors, thermocouples, strain gauges, and medical transducers where high common-mode rejection and low offset are required."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/INA128UAE4","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/INA128UAE4 when reusing this data.
